The 27-song set opened with “It’s So Easy” and delivered a mix of tunes from the group’s catalog over the 2-hour and 45-minute concert.

Prior to playing “Out Ta Get Me,”Axl Rose shared a story of how the band were held up crossing the Canadian border on Friday when customs officials found a weapon on their bus.

“Driving into Canada, we get to the border and we get off the bus,” explained Rose. “They take our passports, they take our phones, and then they come over and say ‘We found a firearm on your bus.’

“’You did what? What?’ ‘Oh, yeah, we found a gun’” he continued. “So we weren’t exactly arrested, we were ‘detained’ for a while. It was kind of fishy. They were very nice. They were very nice. They were very understanding.

“You know, s**t happens - you can forget you had a f***in’ gun,” he said sarcastically before shrugging, “Wasn’t my gun.”

A band representative confirmed the story to Billboard, saying “Yes, this indeed happened on Friday, July 15, as they were crossing the border coming from the Philadelphia tour stop on the 14th.” The gun did not belong to any member of the group, according to the rep.

Guns N’ Roses will next perform the first of two shows with opener Lenny Kravitz at Gillette Stadium in Foxborough, MA on July 19.
